SHF-2UH-LW

The SHF-2UH-LW is a lightweight version of our SHF-2UH gear unit. The SHF gear series features a compact hollow shaft gearhead which has zero backlash as well as exceptional accuracy and repeatability. The gearhead incorporates a Harmonic Drive® gear component into an integral housing. In addition to the hollow shaft, the gearhead also features a high capacity cross roller bearing and output flange to mount the load without the need for additional support bearings. We also have a high torque version, SHG-2UH-LW available.

Key Features:

  • Zero Backlash
  • 20% lower weight than Standard SHF
  • Large Hollow Input Shaft
  • Accuracy <1 arc-min (most sizes)
  • High torsional stiffness
  • Robust cross roller output bearing
  • Output flange for direct mounting of load
